Red and blue tactical recognition flash of theRoyal Artillery.
Atactical recognition flash (TRF) is a coloured patch worn on the right arm of combat clothing by members of theBritish Army,[1]Royal Navy andRoyal Air Force. A TRF serves to quicklyidentify the regiment or corps of the wearer, in the absence of acap badge. It is similar to, but distinct from, theDZ Flashes worn by members of Airborne Forces.
TRFs should not be confused with formation signs or insignia, which are used to denote the formation (usuallybrigade ordivision or a higher headquarters) and are worn in addition to TRFs by a member of any regiment or corps serving in that formation.
Tactical recognition flashes are not to be worn by Cadet Force Adult Volunteers (CFAVs) or cadets of theArmy Cadet Force andarmy section of the Combined Cadet Force irrespective of any affiliation to a Corps or Regiment.[2] Cadets and CFAVs do wear county and contingent flashes of the Army Cadet Force and Combined Cadet Force respectively.[2] All members of the RAF Air Cadets, staff and cadet,[3] wear the RAFAC Cadet formation flash.[4]
